Plumbogummite is a rare lead phosphate mineral with the chemical formula PbAl3(PO4)2(OH)5•(H2O). It forms in oxidation zones of lead deposits and primarily forms as a botryoidal mass after other minerals. The "plumbo" portion of this mineral's name is derived from the Latin word for lead, "plumbum". "Gummi" comes from the gum-like appearance that the mineral often displays.
Pyromorphite is a mineral species composed of lead chlorophosphate with the chemical formula Pb5(PO4)3Cl. It sometimes occurs in sufficient abundance to be mined as a lead ore. It forms small, hexagonal crystals ranging from dark green to yellow and orange.
The lead in pyromorphite can be harmful if absorbed into the bloodstream by inhalation or ingestion. The crystals won't pose a health hazard just sitting on a shelf, but we recommend washing your hands after handling.
